Specification of Letters Patent.

Patented Oct. 15,1907.

Application filed December- 6 1906. Serial No. 346,643.

To all whom it may concern: 7 j I Be it, known that I, BENJAMIN WoLnAUr'rnR, a citizen of the United States, residing at New York city,

in the county of New York and State of New York, have invented certain new and useful Improvements in Insulated hail-Joints, of which'the following is a specification.

' entirely relieving the insulation from the load o weight of the passing train.

The invention primarily has in view an improved construction of insulated rail joint embodying a sectional base plate feature whereby a separate supporting section of base plate is provided'for each rail end, While at the same time admitting of a thorough and complete insulation of the joint throughout without placing the insulation in'positions where it wouldrceive the load or weight of the trains. In this connection, the inven-' tion contemplates a construction which can be advantageously utilized with a separate or detachable base plate of the same ener l type as that embodied in the well knownWolhaupte'r rail joint, while at the same time providing for a novel and effective inter-reinforcing and intersupporting of the variops elements making up the joint to insure afirm and strong base support for each rail end.

Other general objects to be attained by the present invention are the same as those carried out\in connection with the forms of insulated joints disclosed and 1 claimed, in companion applications filed November 8,-

1906 and bearing Serial Numbers 342,523 and 342,524.

The essential features of the invention involx ed in adapting a sectional or two-part base plate construction to joints of the type wherein the base plate is separate and detachable member of the joint, are necessarily susceptible to embodiment in various modifications" without departing from the scope of the invention, but for illustrative purposes there are shown in the drawings certain preferred practical modifications of the invention. I

In these drawings Figure 1 is a sectional perspective view of a rail joint constructed in accordance with the "present invention and illustrating the improvements the'line 4,-4 of Fi 1. Fig 5'is-a longitudinal sec- 7 tional view on the line 5-5 of Fig. 4, illustrating the insulated coupling connection between the separate base sections, and also showing the one end base insulating feature in combination with the insulating end post which is utilized as an insulating medium between the adjacent inner edges of the separate base plate sections. l?ig. 6 is a sectional perspective view showing the improvements in their application to a' type'of joint embodying opposite angle bars as the side girder members of 'the' joint. ,Figs. 7 and 8 are views-similar to Figs. 2 and 3 respectively of the opposite side. girder I members and their related parts of the form of joint shown in Fig. 6 of the drawings. 9 is a. detail perspective view showing a modification that may be re-'- sorted to inproviding for the support of one edge of a' base plate section upon the inner edge portion of a side girder member.

, "Like reference characters designate corresponding parts in the several figures of the drawings.

A prominent and distinctive feature of the present invention resides in constructing a rail joint with a sectional or two-part base plate and so arranging the parts that each section of the base plate affords a metal supporting base for each rail end, while at the same time the separate sections of the base plate are coupled or fastened together so as to constitute in effect one base plate common to both rail ends in the sense thateach section of the base plate has a support from both of the side girder members or side joint plates, thereby securing an effective 'reinforcing and strengthening of the basesupport throughout.- At the same time the sectional or two-part base plate construction referredto preserves that advantageous feature of the companion the embodied in a variety of rail joint structures withticular reference will now be made out affecting the essential features of the invention, but

the improvements claimed are 'well exemplified in the forms ofjoints shown in the drawings and to which par- Referring to the form of insulated rail joint shown in Figs. 1 to 5 inclusive of the drawings, the said joint includes in its general organization the adjacent servicev or running rails 1 and 2, the oppositely arranged side joint plates} and 4, the joint bolts 5, and a sectional or two-part base plate consisting of the separate individual base ' plate sections 6 and 7, each of which affords-a direct metal bearing support for one of the rail ends.

The ter ide joint p1at i the sense employed of the joint irrespective ofthe design or formof these members, so it will be understood that these' girder members may consist of any ofthe conventional forms In tlfeform of the invention shown in Fig. 1 of the drawings, the side girder members 3 and 4 are inclined from a vertical plane. so as to engage with the correspondingly inclined outer bearing faces 8 of theoppositely located filler blocks 9 and '10 which are respectively arranged at opposite sides of the rail ends and interposed between the latter and side girder members '3 and A. By reason of the complelnental and'cont'act ing relation of the inclined bearing faces 8 of the filler blocks, and of the inclined girder members 3 and 4, it

will be understood that when the said girder members are drawn togethenor tightened upon the blocks 9 and 10 through the action of the'joint bolts 5 or otherwise, the tendency of the girder members is to slide upward upon the said bearing faces 8 with the result of exerting a lifting force upon the base plate 67 so as to draw the same into .firrn supporting contact with the rail bases.

In adapting the inclined side girder members 3 and 4 to the present invention, it is necessary to provide an even bearing support for the heads and nuts of the joint bolts 5, as well as to scdure a thorough insulation thereof: To secure this result, apractical construction which may be resorted to is shown in Fig. lot the drawings and consists in fittingwithin each bolt hole 11 of the girder members an offstanding metal bevel washer 12 of tubular form and affording upon its outer end straight bearing for the flange or head of a flanged insu letting-bushing 13, between which latter and theheads andnuts of the bolts are interposed the usual metal backing-washers 14. Of course other insulating expe-- dints may be resorted to for insulating the bolts from the girder members and rails Without departing fro'm' the present invention.

Each of the girder members and 4 is provided at its lower edge with. an outturned spiking flange l5 and with an inside inwardly projecting base supporting I flange 16 preferably extending longitudinally from end porting flange 16 mi y bel provided in various ways and may be of lesseictent than the girdermember. Also,

the said fian ge may be variously formed, such for'in-,

stance, as simply consisting-of a plain inwardly projecting flange or lip as shown in detail in Fig. 9 of the drawings, or being embodied in more of a grooved for- 'mation as shown in other figures of the drawings, but 5 in any design, and with the flange 16 of any proper length, the same affords a direct supporting surface upon which a section of the base plate is held and carried.

Indesigning the individual sections of the base plate for 'engagement'wi'th and support by the girder members, it is preferable to provide each of said sections of the base plate along one of its-longitudinal side edges with an angled offset holding flange 17..arra.nged in 'parallelism to the top portion of the plate section and producing along its inner I edge a rail bearing shoulder 18 lying'above the plane of the top surface, of the section oi the base plate and adapted to engage against the edge of the rail base on base flange as plainly shown in Fig;

'1 of the drawings in a manner similar to the detachable orseparate base plate of the Wolhaupter type of rail joint."

The offset holding flange 17 of'each-section of the base plate is adapted to take over and rest upon the supporting flange 16 of the side girder or girder member with which such plate section is associated. This when the girders are drawn together, while at the same ftiine permitting the sectionof the base plate tofbe detached or separated from its girder in contradistinction to those types of joints wherein the individual sections of the base plate are rigid or integral with the side plate or g irder member as described and illustrated in the- /companion applications aforesaid.

In carrying out the present invention, the same preserves the idea of each-section of the base plate having a direct supporting engagement with only one of the side girders. Hence, with this arrangement, the sec-' tion of the base plate for each side girder member is usually of a length approximately equaling one-half the full length of said girder member, though this may be varied to suit conditions where the joint is to be applied, However, in all forms of the invention, each section of the base plate is located wholly atone side of the transversecenter of its supporting girder so thatsuch girder carries a section of the base plate along one end portion thereof. I

. The separate sections of the base plate 6-7 are preferably duplicates in design and'arrangement and are disposed.'respectively at opposite sides of the transverse-central line of the joint as plainly shown in Figs. 4 and 5 of the drawings. Hence,- by reason of this arrangement, the separate sections of the base plate lie in the same horizontal plane and in spaced matching plished by providing ,a' fastening connection between i the inner adjacent ends of the separate sections'of the base plate which are respectively supported upon the opposite girders. This fastening connection isintended to provide a rigid union between the two sections of the base plate, while at the same time thoroughly insulating such sections so that, each of the same may be said to afford each rail end a support on .both sides ofthe meeting'point of the rail ends without inetallic contact or electrical connection with the corresponding section of the base plate. A construction which may be utilized for accomplishing this result involves the provision of each section of the base plate atits inner end with a pendent transversely disposed terminal flange 19 which necessarily acts as a stiffening girder or flange while at ,the same time being provided with one o r a plurality of bolt holes 20 receivingthe coupling bolts 21 which are arranged to connect the terminalilanges 19 of both plate sections 6 and 7. AthorOughirisula- 'tion of the fianges19 and ofeach bolt may be secured by incasing the latter in an insulating bushing 22 extending into the bolt holes 20, andby arranging insulating washers 23 between the heads and nuts of the ends, while at the same time thoroughly insulating the two sections of the base plate from each other.

I In thejconstruction described, with each sectionoi' the base plate resting upon a track tie T, it will be'ob; view that the base plate 67 performs the functions.

of a single base plate for both rails, while at the same time being supported by two girders and by two ties.

This secures a most effective inter-re nforcing and.in--

tersupporting oi" the partsv and greatly increases the supporting effect of the individual sections of the base plate for each rail end.'- 1

To-complete the insulation of the joint described, the insulating-end post 25, between the rail ends 1 and 2, may be arranged to extend below the bases of the rails so as to project into the gap or interval between the inner adjacent ends of the sections 6 and 7 of the base plate, thus securing an effective insulation atthis point. Complete insulation between the free longitudinal edge, or the unattached longitudinal edge, of each section of the base plate and the opposite girder may be'secnred by employingan insulating angle strip 26 whose horizontal flange may be conveniently held for support on the flange 16 of the girder, while the pendent flange oi the said strip lies in the interval be tweensaid girder and the opposing unattached edge of the opposite sectioh oi the base plate. he twoinsulatingfistrips 26 are arranged along what may be termed the on-supporting ends of the girders and hence aredisposed in diagonally opposite'relatioii as. shown Fig. 4 of the drawings, thereby providing a one-end insulation 'betu een' each posing section oi the base plate.

The essential features of the invention above pointed out maybe embodied in'various forms of joints, such girder and the opfor instance as the type-of joint shown in Figs. 6 toS,

inclusive, of the drawings. In this embodiment of the invention the same general features are preserved as already set forth, but the side girder members, instead of being in the form of inclined side plates cooperating with filler blocks, are of the angle bar type, the same being designated by the reference characters 27' and 28 respectively. The angle bar girders 27 and 28 may be of the general conventional form and each oi thesame is provided at its lower edge with a spiking flange 15 and an insulated base supporting shoulder 16 preserving the same functions and cooperating with the same parts, as the corresponding elements described in connection with the construction shown in Figs. 1 to 5 inclusive of the drawings.

. In adapting the improvements of the angle bar type to the joint shown Fig. 6 of the drawings, a properinsulation between the angle bars or girders and the sides ofthe rails is secured by the employment of the usual sheet insulation 29 interposed between the rail -6 5- sides and the angle bars or girders so as to thoroughly insulate theadjoining faces of th'e rails, of the said bars. Also, in this construction,any suitableexpedients may be resorted to for insulating the joint bolts5,

tially the same insulating expe'dients, with the exception of the bevel washers 12, as shown in connection with the heads and nuts-oi the belts in Fig.- 1 of the drawings; In other respects, the form of joint shown in Fig. 6 of the drawings is substantially the same in all respects as the form illustrated in Fig; 1, and hence I similar reierence characters will apply to similar parts. --in'the two forms.

to those skilledin the art, and it will be understood that various changes inthe form, proportion and minor details 'of construction may be resorted to without departing from the spirit or sacrificing any of the advantagesof the invention.
